“We the undersigned, senior members of the world’s scientific community, hereby warn all humanity… A great change in our stewardship of the earth and the life on it is required if vast human misery is to be avoided and our global home on this planet is not to be irretrievably mutilated.” (UCS, World Scientists’ Warning to Humanity 1992)
“At the heart of this assessment is a stark warning. Human activity is putting such a strain on the natural functions of the Earth that the ability of the planet’s ecosystems to sustain future generations can no longer be taken for granted.” (MEA, Living Beyond Our Means 2005)
